If you're undergoing orthodontic treatment with clear aligners, you know how important it is to keep them clean. Properly cleaning your aligners not only ensures they stay clear and free from bacteria, but it also contributes to your overall oral health. Dirty or improperly cared-for aligners can cause unpleasant odors and stains and even lead to oral health issues like plaque buildup or gum irritation.
In this guide, we'll explain the best methods for cleaning your aligners so they remain in top condition throughout your treatment, keeping your smile fresh and oral health intact.
Aligners are designed to be worn for 20–22 hours a day, so they’re constantly in contact with your teeth and mouth. Food particles, bacteria, and saliva naturally build up on the aligners as you eat, drink, and talk. If not cleaned regularly, this buildup can cause several problems:

Following a consistent and straightforward cleaning routine ensures your aligners stay in excellent condition, giving you a cleaner, healthier smile throughout your orthodontic journey.
To maintain clear, fresh aligners, follow these easy steps every day:
Start by rinsing your aligners under cool water to remove loose particles, saliva, and food debris. It's important to rinse your aligners immediately after removing them to prevent any buildup from settling. Avoid hot water, as it can warp the plastic material of your aligners.
Use a soft-bristled toothbrush (separate from your regular toothbrush) and a mild, unscented soap or denture cleaner to clean your aligners gently. Avoid using toothpaste, as it can be too abrasive and may scratch or cloud the surface of your aligners. A soft brush helps remove plaque, bacteria, and food particles without damaging the plastic.
Soak your aligners regularly to clean them and prevent bacteria buildup thoroughly. You can use solutions specifically for aligners, like Invisalign cleaning crystals or a denture cleaner. Soaking your aligners will help keep them free from stains and bacteria, ensuring they remain clear and fresh.
Dissolve the cleaning solution or crystals in a small container of lukewarm water, and soak your aligners for about 15–20 minutes. After soaking, rinse them thoroughly with cool water before placing them back in your mouth.
Once your aligners are clean, give them a final rinse with cool water to ensure all cleaning products are removed. Then, let your aligners air dry before putting them back in your mouth or storing them in their case. Avoid using hot water or a towel to dry your aligners, which can cause warping.
If you're looking for alternative cleaning methods, there are a few at-home remedies that can help maintain your aligners:
Mix baking soda with water to create a simple paste. Gently brush your aligners with this paste to help remove stains and odors. Baking soda is a natural cleaner and a great option for deep cleaning without damaging your aligners.
Dilute hydrogen peroxide with water (1 part hydrogen peroxide to 3 parts water) and soak your aligners briefly. This solution helps to remove stains and disinfect your aligners. Rinse your aligners thoroughly after soaking to avoid any leftover residue.
You can also use white vinegar as a natural cleaner. Dilute it with water (1 part vinegar to 3 parts water) and soak your aligners for about 15 minutes to help remove buildup and stains. As with hydrogen peroxide, rinse your aligners thoroughly to prevent any vinegar taste.
While keeping your aligners clean is crucial, there are a few key tips you should keep in mind to protect them from damage:
The key to maintaining clean aligners is consistency. Make it a habit to clean your aligners twice daily, after meals, and store them properly in their case when you're not wearing them. This consistent care will keep your aligners looking great and ensure they effectively straighten your teeth.
Proper cleaning of your aligners is essential for maintaining your oral hygiene and their appearance. Following the cleaning steps outlined in this guide, such as rinsing, brushing gently, soaking, and avoiding harsh chemicals, you’ll keep your aligners fresh and functional throughout your treatment.

No, it's best to avoid using toothpaste to clean your aligners. It can be too abrasive and may scratch the surface, causing damage and discoloration. Use a mild soap or a denture cleaner instead.
Soak your aligners at least once daily in a cleaning solution to remove bacteria and prevent staining. You can also soak them more frequently, especially if you notice buildup or odor.
While mouthwash may seem like an easy solution, the chemicals in many mouthwash brands can cause your aligners to discolor over time. The best solution is to use mild soap, denture cleaner, or specialized aligner cleaning solutions.
